Answer 2

Sure, I can help you solve these equations. Let's go through each one step by step:

1. 2x - 10 = 0 Add 10 to both sides: 2x = 10 Now, divide both sides by 2 to find the value of x: x = 10 / 2 x = 5

2. 1.4x - 12 = 0.9x + 4 To solve for x, first, let's bring all the terms with x on one side and constants on the other side: 1.4x - 0.9x = 4 + 12 0.5x = 16 Now, divide both sides by 0.5 to find the value of x: x = 16 / 0.5 x = 32

3. 3x + 14 = 5x + 16 Subtract 3x from both sides: 14 = 2x + 16 Now, subtract 16 from both sides: -2 = 2x Finally, divide both sides by 2 to find the value of x: x = -2 / 2 x = -1

4. 12 - (5x + 10) = -3 First, distribute the negative sign: 12 - 5x - 10 = -3 Combine like terms: 2 - 5x = -3 Now, subtract 2 from both sides: -5x = -5 Finally, divide both sides by -5 to find the value of x: x = -5 / -5 x = 1

5. 6 - (8x + 11) = -1 First, distribute the negative sign: 6 - 8x - 11 = -1 Combine like terms: -5 - 8x = -1 Now, add 5 to both sides: -8x = 4 Finally, divide both sides by -8 to find the value of x: x = 4 / -8 x = -0.5

6. (3x - 4) - (6 - 4x) = 4 Let's first perform the operations inside the parentheses: 3x - 4 - 6 + 4x = 4 Combine like terms: 7x - 10 = 4 Now, add 10 to both sides: 7x = 14 Finally, divide both sides by 7 to find the value of x: x = 14 / 7 x = 2

So, the solutions to the equations are:

1. x = 5
2. x = 32
3. x = -1
4. x = 1
5. x = -0.5
6. x = 2
